Dinar-c DEVICE.

To all, whom it may concern;

, Be it known that we, CfiARLEs H. Dow and WILLIAM L. BURNER, citizens of the United .States, residing at Columbus, in the county ofFranklin and State of Ohio, and JoHN M. WILOOX, a citizen of the United States, residing at Cleveland-in thev county of Cuyahoga and State of Ohio, have invented certain new and useful Improve ments in Dump-Car'Devices, of which the der. Essentially a rod associated with the is almost j completed. This engagement valve adapted to 'co'ntrol'the supply ofair" to the cylinder is: disposed in the cylinder to be engaged by the piston .when the necessary travel of the piston to dump thecar causes the valve .to' be rotated and the supply of air to the cylindcris' cut ofl".

. The purpose of the device is to economize air by cutting oil the flow when the need for it is past.' In practi'ceit often happens that one car ina train requires less air than another todump, and the supply to each car should therefore be automatically controlled to lessen the expense of operation.

In the drawings is shown a construction in which a cylinder is positioned about the l longitudinal middle of each side of the car,

and the dumping impetus is imparted midway of the ends; in the pipin valve is provided associated wit arod or member penetrating the cylinder to receive the impact of the moving 'latter is approaching the unit of its out- Ward or dumping movement, whereby the valve is turned to its out ofi position. Other constructions to accomplish this result may be made, and the construction illustrated is intended toshow merely a preferred embodiment of the ideaI Referring to the drawings which accompany this description and are hereby made a part of this specification, Figure 1 is a side view of a car having the improved devices thereon; Fig. 2 is a view partly in section of the valve and tripping devices therefor .associated with an air cylinder.

grai ged to dump laterally to discharge the contents; the cylinder 3 is appropriately placed on the'frame 1, and contains the pis-' ;ton 4, having the stem 5 adapted to be reciprocated to dump the car. Air is admitted to thegu'nder-side of the piston through the pipe'fi from the pipe 7 through the passage- ;way '8, which is controlled by the valve 9 izplacedftherein, and adapted forrotation to ;admit the air into pipe 6 or to exclude it therefrom. The valve stem 10 carries the rocker arm 11, with which is pivotally associated the link 12; at 13 the link 12 is pivoted to the stop 14 carried on the rod 115. The stop 14 rests on the bracket 16 when the parts are normall positioned.

The rod 15 is encircledby t e spring 17,

and passes. through the uide 18 near its ,upper end and through the bracket lfinear its lower end; the spring is compressed between the stop 14 and the guide 18 when the rodis: lifted, and by expansion tends to return the rod 'to normal position when the stress thereon is intermitted; At its upper end the rod 15 is hooked and inserted t-hroughthe cylinder top at 19, to project downwardly in the cylinder as appears at 20.

Eor the details of a construction for 'duifnpin the car reference is hereby made to the pen ing application of Messrs; Stansill,

Dbty, and Hubbard, Serial Number 511,662, filed 1n the United States Patent Ofice on August 6th, 1909; it is in connection with f mp g devices of the general kind there, in illustratedthat we contemplate the us of the improvements herein set forth, al-' though it is apparent that they may be used in connection with any dumping construction employing compressed air or other kind of motive pressure.

The operation is as follows:--Air admitted into the cylinder through pipe 6 lifts the piston 4 and the stem 5 is operated to dump the car. When the upper face of the piston 4 contacts with the end 20 of the rott 15 the latter is lifted and the rocker arm 11 is rotated, thereby closin the valve 9, and the unnecessary further in ow of air is prevented. The air in the cylinder at the moment of contact between the piston and rod is sufficient to complete the dumping of the car, and the parts are so regulated that merely enough air is admitted to'cause the car to dump; All the cars may have equipl-lll out the train. 'Changes in the'positic'ns of parts, not necessary to describe here, are

now effected in the valve construction shown generally at 2l, to cut ofi the communica- ,bedthese operations tion between pi es 6 and 7 and to. permitthe exhaust of air from thecylinder3 there;

spring. The valve 9. is again turned to'its'i open position by-the return movement of,"

the rod 15, and the foregoing operations; arerepeated.

The device herein described "may be ap plied to each side of the car, and in use. that arrangement would usually be carried out; it is seen thatthe righting of' the car bed would be accomplished in the same manner as the dumping, except, ofcourse, inafp'articu-lar dumping and righting-Poi the-car are accomplished through cylinders arranged v on opposite sides of the car, 7 Consequently, economy of air is effected in the righting operation, and in all essential respects the two operations are performed in the same manner andby identical means. Cars are accordingly'built, with both sides equipped with the device herein shown and described.
